Past and uniformed thinking attributed the articulation of the sacroiliac and spinal joints solely to muscles. If you believe this, name one muscle capable of driving the sacroiliac joint articulation?

The pelvis and spine articulate by making use of gravity, and pelvic side shift and muscle. Discover how, in my book Advanced Osteopathic Technique.
